Study On The Configuration Of Terrestrial Herb In Landscape Design Under The Theory Of Sponge City

Under the background of building the sponge city system in our country,the combination of landscape design and sponge city system will be beneficial to the improvement of urban ecological environment,water resources reasonable developments,alleviation of urban rain disasters,and create a beautiful and comfortable living environment to local residents.By giving full play to the usage and studies of plants in landscape design,which has vital significance to the construction of the sponge city.The sponge city construction is still in the initial phase in our country at present time,there is little targeted research for the configuration design of sponge plant,so this article focuses on the research of sponge terrestrial herbaceous plants configuration in the landscape design under the theory of sponge city.Take nanjing area for example,the article studied the common configuration design of several terrestrial herbs in landscape design in nanjing area.This paper was mainly divided into three parts.The first part,the paper introduce the related concepts analysis of sponge city,terrestrial herbs design,plants landscape design and the plant configuration research and case analysis of city landscape design under the background of sponge city design.Discussed the landscape design method of sponge city construction,corresponding research of the landscape plant configuration design in sponge city construction,including the significance and function of plant usage in sponge city construction,selection principle of sponge plant and the application of terrestrial herbaceous plants in the sponge city,then finally expounded by the cases accordingly.Second,determine the research area and analysis of relevant factors of investigation contents in this paper.Including analysis of roads,plant configuration and rainfall climate in nanjing area;Which also include some commonly-used terrestrial herbaceous plants purify ability of landscape planting in nanjing area,with economic cost,operational and effective experimental operation,it determine the strength of the purification ability of such plants,provided supporting data for the rest half of the case practice.In the third part,theoretical research for practice of the case-Nanjing Xianlin Avenue planning and design,use case test theory of rationality of science and research.An important role in mastering the sponge city construction points,plants in the sponge in the city construction especially in terrestrial herbaceous plants and its configuration,clear design ideas,combined with field condition on vehicle greenbelt,green belt trees and land side of the green belt with the landscape design method of city planning and design of the sponge,focusing on the Nanjing area commonly used terrestrial herbaceous plant configuration design in the application.Complete the theory to the practice of exploration.
